The anion exchange reactions of Cl-macrocycle 1a [(p-MeO-C6H4)(2)Te)(2)(mu-O)(mu-PhSeO2)(mu(4)-Cl)](2) with AgNO3, AgClO4 and AgBF4 yielded colourless solids whose single crystal X-ray diffraction studies revealed the formation of 12-membered macrocycles [(p-MeO-C6H4)(2)Te)(2)(mu-O)(mu-PhSeO2)(mu-X)](2) [X = NO3 (2), ClO4(3), BF4(4)]. ESI-MS studies revealed that macrocycles 2-4 retain their integrity in solution. The solution Te-125 NMR spectrum of 4 shows the appearance of a triplet ((1)J(Te center dot center dot center dot F) = 568 Hz) that can be assigned to coupling between Te-125 nuclei and two fluorine atoms in BF4- ions.
